Practical benzylation of N,N-substituted ethanolamines related to chemical warfare agents for analysis and detection by electron ionization gas chromatography–mass spectrometry

The benzylation of three low molecular weight N,N-disubstituted ethanolamines related to chemical warfare agents (CWAs) to furnish derivatives with improved gas chromatography-mass spectrometry (GC-MS) profiles is described. Due to their low molecular weight and polar nature, N,N-disubstituted ethanolamines are notoriously difficult to detect by routine GC-MS analyses during Organisation for the Prohibition of Chemical Weapons (OPCW) proficiency tests (PTs), particularly in scenarios when they are present at low levels (~1–10 ppm) amidst more abundant interferences. Our studies revealed that the optimal derivatization conditions involved the treatment of the ethanolamine with benzyl bromide in the presence of an inorganic base (e.g., Na₂CO₃) in dichloromethane at 55°C for 2 h. This optimized set of conditions was then successfully applied to the derivatization of N,N-dimethylethanolamine, N,N-diethylethanolamine and N,N-diisopropylethanolamine present separately at 1 and 10 μg/mL concentrations in a glycerol-rich matrix sample featured in the 48th OPCW PT. The benzylated derivatives of the three ethanolamines possessed retention times long enough to clear the massive glycerol-containing matrix interferences. The protocol herein is introduced as an alternative method for derivatization of these CWA and pharmaceutically important species and should find broad applicability in laboratories where routine forensic analysis is carried out.     

The effects of certain intermediary target materials and their proximity to ballistic gelatin on jacketed hollow point bullet expansion

Expanding bullets are preferred by law enforcement because of their wounding potential and ability to avoid over-penetration which could result in unintended targets being struck by bullets that perforate their intended targets. Expansion failure for jacketed hollow point (JHP) bullets is commonly attributed to several causes including damage to the bullet's cavity, velocity loss, bullet destabilization and materials from intermediate targets filling the bullet's cavity which can cause expansion failure when the bullet subsequently impacts a soft, fluid-based target such as human tissue or ballistic gelatin. In this study, JHP bullets were fired into ballistic gelatin after passing through selected intermediate targets representing items common to shooting incidents. Velocity loss and bullet destabilization were not factors that contributed to the JHP bullets that experienced expansion failure; however, materials obstructing the bullets' cavities and damage to the bullets' cavities were considered causes for some of the JHP bullet expansion failures. It was determined through this research that most of the target materials caused JHP bullet expansion failure when shored against the ballistic gelatin, but when placed at distances of 7 ft. from the ballistic gelatin, bullets fired through the same target materials did expand. This original and unique study produced findings that are of significant value to shooting incident reconstruction experts and other forensic professionals as shooting incidents can call into question a victim's proximity to a wall or door when a bullet(s) perforated such a target material.     

The penology of racial innocence: the erasure of racism in the study and practice of punishment

In post–civil rights America, the ascendance of “law-and-order” politics and “postracial” ideology have given rise to what we call the penology of racial innocence. The penology of racial innocence is a framework for assessing the role of race in penal policies and institutions, one that begins with the presumption that criminal justice is innocent of racial power until proven otherwise. Countervailing sociolegal changes render this framework particularly problematic. On the one hand, the definition of racism has contracted in antidiscrimination law and in many social scientific studies of criminal justice, so that racism is defined narrowly as intentional and causally discrete harm. On the other hand, criminal justice institutions have expanded to affect historically unprecedented numbers of people of color, with penal policies broadening in ways that render the identification of racial intent and causation especially difficult. Analyses employing the penology of racial innocence examine the ever-expanding criminal justice system with limited definitions of racism, ultimately contributing to the erasure of racial power. Both racism and criminal justice operate in systemic and serpentine ways; our conceptual tools and methods, therefore, need to be equally systemic and capacious.     

Moral economy in a global era: the politics of provisions during contemporary food price spikes

The wave of food riots since 2007 revived interest in why people protest in periods of dearth, yet research has to date failed to make sense of the political cultures of food protests. The concept of the moral economy in European history is explored here to make sense of contemporary political perspectives on how food markets should work in Bangladesh, Indonesia, Kenya and Zambia. The concrete expressions of these moral economies are localized and politically contingent, yet there are broad areas of common ground across settings. As with the moral economies of seventeenth- and eighteenth-century Europe, there is strong popular feeling against speculation and collusion in food markets in times of dearth, and an emphasis on the responsibilities of public authorities to act. But whereas the moral economy in European histories focused on customary paternalistic obligations, the contemporary emphasis is on formal and electoral accountabilities as a means of triggering public action. The paper concludes with a discussion of a research agenda on the moral economy and the politics of provisions in globalised present-day food markets.     

(In)Visibility and the Display of Gendered Desire: Masculinity in Mainstream Soft‐ and Hardcore Pornography

This article discusses different features of heterosexual soft‐ and hardcore pornography from the perspective of heterosexual masculinity and (in)visibility. It examines the embodiment of sexuality through the female body in lads' softcore magazines and the position of the phallus and the male body in some hardcore magazines and films. The article takes its startingpoint from notions of the problematic relationship between the depiction of the male body and desire, arguing that different visual techniques are used in sexual settings in order to maintain the status of the male (primarily white) body and the penis as being particular and distinct from other bodies.     

Social Reconstruction as a Local Process

¹When it comes to post-armed conflict interventions aimed atrestructuring a shattered society, policy makers have largelytreated countries as an undifferentiated whole, ignoring localdynamics that reinforce or transform the power relations thatare often most relevant to peoples’ lives. Using the exampleof Guatemala, the authors argue that local-level, bottom-upmechanisms can reflect a country's diverse makeup and experienceof conflict, and provide crucial precursors or extensions forwider-scale national and international projects. Local-levelinitiatives also can involve more community members, promoteagency and perhaps be less prone to large-scale patronage andcorruption. In promoting truth-telling initiatives and confrontingthe past, memorializing the departed and burying the dead, andresolving ongoing or recent community conflicts, the authorshave found that local-level programs have distinct advantages.The article considers local ‘houses of memory,’community-sponsored psycho-social interventions and exhumations;and conflict resolution based on Mayan methods. It concludesthat such efforts should be more systematically identified andsupported in post-armed conflict settings. In transitional justice,as elsewhere, the authors find, all politics is local.     

Sentencing Female Drug Offenders: Reexamining Racial and Ethnic Disparities

This study analyzes the relationship between race/ethnicity and sentencing outcomes for female drug offenders in Florida. Grounded in the focal concerns perspective, the research examines whether, in the specific case of drug offenders, minority women are treated more harshly than White women. Interaction models are estimated to determine the influence of drug offense type on racial and ethnic sentencing disparities. Differences in sentencing outcomes are also examined following significant policy changes in the state. In general, the findings suggest that minority female drug offenders are disadvantaged at both the incarceration and sentence length decisions. It also appears that perceptions of dangerousness associated with female offenders' race/ethnicity and offense are incorporated into sentencing authorities' patterned responses. That is, the level of disparity between Black, Hispanic, and White females is conditioned by type of drug offense in the interaction models. The changes in sentencing policy also impact the role of race and ethnicity in sentencing decisions. By analyzing drug offenders exclusively, the current study clarifies the role of race in sentencing decisions for females. In contrast to prior research that examined all offense categories together, the current study suggests that for drug offenses, minority females may, in fact, be deemed more dangerous and culpable than White female drug offenders.

公平原则及相关情况规则探讨——兼析中国东海大陆架划界基本主张

新近,国际法院在相关的司法判例中提出了公平原则及相关情况规则,尤其在2009年罗马尼亚诉乌克兰黑海划界案中确认了这一具体规则及其适用方法。该项规则是建立在公平基础之上的,相比其他划界方法而言,更强调原则的属性。实际上,公平原则常常使用各种方法的结合以便取得公平结果。由于公平原则在划界领域可以平衡各种公平因素,因此在海洋边界划分中具有习惯法的地位。据此原则,中国有关东海大陆架划界的基本主张不容置疑。
